This is more of a Linux question than a PROIV question directly.

Original working system: PROIV version 1.5103 on SCO Unix Release 5

Upgrading to Fedora Core 5 (or ES 4) with PROIV version 5.5 Rev 3.4.0

Device is a Genovation 100 key keypad with LCD display.

This system is for Point of Sale and the keypads are attached to cash registers. 2 character ASCII codes are sent to PROIV and PROIV sends back information to display on the screen. Treating the screen as a typical tty login. In the working system we use hex code escape commands (82h, 84h etc..) to cause the screen to allow for printing, clearing etc... In the new system, this doesn't seem to work, yet I have verified that the multiport serial card does work and the keypad works with the testing software that came with it. The general principal is to sent stdout to the LCD screen from a temp text file created by PROIV.


Thanks in advance
